Why do some courses never come up for review?

I have several Italian courses which never seem to come up for review. Because I’ve completed so many, I only review courses when prompted to. Recently looked through older courses and realised I’ve forgotten some words because I’m not prompted to review.

Anyone know why this is? A clumsy solution is to go through each course and do a classic review, but this kind of defeats the whole purpose of Memrise to keep your list of memorised words up-to-date.

Hi calvin, here’s a quick explanation on how words needed for reviewing are calculated:

Memrise calculates words that requires reviewing as words you have forgotten. The algorithm predicts when a given word would have fallen out of your long term memory.

You can also check when words are due to review by going into each individual level on the website.

Below is a screenshot of a level which requires reviewing. Notice on the right side, there is a water icon which has the text, “now” written beside it. This means the word is due for reviewing.

Below is a different screenshot, which informs you when next the word will need to be reviewed. The more times you correctly review the word, the longer it takes for the word to be due for reviewing.

For any word that you always get correct, this is the review schedule:

  • Plant/learn: review again in 4 hours
  • First review: water/review again in 24 hours
  • 6 days
  • 12 days
  • 24 days
  • 48 days
  • 96 days
  • 180 days
  • 180 days
  • 180 days, etc

If you get a word wrong during the planting session, it will come due in 4 hours, and then 12 hours. After that, it follows the normal schedule if you always get it right. (24 hours, 6 days, and so on.)

In some courses, if you plant, and then don’t water for 24 hours or more, Memrise adds an extra watering session. (4 hours, 12 hours, 24 hours, 6 days, etc.)

Later, after you’ve watered an item a few times, if you get it mostly right (maybe you had a typo), it will come up for review in 4 hours, and then return to the normal schedule. (For example: plant, 4 hours, 24 hours, 6 days, got it mostly right, 4 hours, 12 days, etc)

If you get it completely wrong during a watering session, the schedule starts over as if you’re planting. I’m not sure if it includes the extra watering at 12 hours or not.

If completed your Italian courses 4 months ago or more, most of your words in those courses are probably at the 96-day and 180-day interval, so they won’t come up often.

Many thanks, both, for the helpful replies. It goes a long way to explaining my situation. However, I do wonder if there is a bug somewhere for several of these courses, as some words never come up, even after a year.

Did you ignore any of them? That would prevent them from showing up in a review…

You can go into the course on the web and look at it level by level - for each word, it should show you how long until the next review. If you keep a tab open and reload it the next day, you should see all the numbers decrease by one day.

So I mostly do multiple choice courses and I often intentionally answer wrong to reset the reviewing schedule. After that I answer correctly again (in the same reviewing session).

Do you know if that actually resets the reviewing schedule back to zero? I would feel cheated by Memrise if it didn’t. It then wouldn’t do the one thing I use it for: spaced review that makes sense.

@Arete_Hime - In my experience, getting multiple choice answers counts as a completely wrong answer and resets the review schedule. In that case, the watering schedule is either 4 hours, 12 hours, 24 hours, 6 days, 12 days, etc… or 12 hours, 24 hours, 6 days, 12 days, etc… or 4 hours, 24 hours, 6 days, 12 days, etc.

Answering wrong a word in speed review resets the reviewing schedule?

in the web version it does

I know this is an old thread, but I was interested in the link (/524537-website-learning-performance-explained) but it didn’t open. If there is a new location for this page, what is it?

Thanks!
